For Renny Rogers, it was strange enough that military jets were flying low over his home in Waldorf in the middle of the night. It was what he thinks he saw when he headed outside to look early yesterday that floored him.

"It was this object, this light-blue object, traveling at a phenomenal rate of speed," Rogers said. "This Air Force jet was right behind it, chasing it, but the object was just leaving him in the dust. I told my neighbor, 'I think those jets are chasing a UFO.' "

Military officials confirm that two F-16 jets from Andrews Air Force Base were scrambled early yesterday after radar detected an unknown aircraft in area airspace. But they scoff at the idea that the jets were chasing a strange and speedy, blue unidentified flying object
